"Breaking Dawn," the fourth and final novel in the "Twilight" series, arrives in stores this weekend, concluding the vampire romance that's been keeping readers up all night since the series debuted in 2005. The books have a monster hit among young adults and beyond, with the first novel, "Twilight," selling 3.5 million copies, and "Eclipse," the third installment, topping even "Harry Potter" on the bestseller list. A film adaptation is due in December.

It's all been a lot to take in for author Stephenie Meyer, a wife and mother of three who told CBS News she never expected she'd be published - much less writing bestsellers.
